[0003] The existing drilling rig generally adopts the structure of the kelly and the turntable in the lifting device part. The wire rope is wound by the winch, and then the wire rope passes through the crown block, etc. to drive the hook to lift or lower the pipe string. This kind of kelly and turntable The structure is complex, the volume is large, and the steel wire rope needs to be checked and replaced regularly, which poses a safety hazard; at the same time, the driller on the drill floor needs to hold the brake handle by hand when sending the drill, which is not only labor-intensive, but also low in work efficiency; in addition, now Generally use the old-fashioned tower derrick, which is large in size and occupies a large area

The invention discloses a chain type top drive drilling machine. The chain type top drive drilling machine comprises a base, derricks vertically fixed to the base, a bit feed device which is arranged on the derricks and moves vertically and a top drive device hung under the bit feed device. A guide rail with a groove structure is arranged in the middle of each derrick, and chains are fixed to the inner walls of the same side of the guide rails. The bit feed device comprises a bit feed drive device and two chain wheels, the two chain wheels are meshed with the chains respectively, the bit feed drive device is connected to the two chain wheels through a bit feed transmission mechanism, and limiting mechanisms are fixedly arranged on the upper side and the lower side of the bit feed device. The top drive device comprises a top drive driving device, the top drive driving device is connected to a drill stem nipple through a top drive transmission mechanism, a lifting ring angle rotation device is arranged on one side of the top drive device, and a lifting ring is arranged on the lifting ring angle rotation device. The base is provided with a back-up wrench. The chain type top drive drilling machine is simple and compact in structure, convenient to install, small in size, safe and reliable, and can lower the labor intensity of workers and improve the work efficiency.
Description
technical field [0001] The invention relates to a drilling rig, in particular to a chain type top drive drilling rig. Background technique [0002] The oil drilling rig is an important equipment in oil exploration and development. The drilling rig drives the drilling tool to drill underground, breaks the rock at the bottom of the hole, and lowers or raises the drilling tool in the hole. Existing methods for hoisting pipe strings generally use winches, cranes, wire ropes, hooks, etc. to lift. [0003] The existing drilling rig generally adopts the structure of the kelly and the turntable in the lifting device part. The wire rope is wound by the winch, and then the wire rope passes through the crown block, etc. to drive the hook to lift or lower the pipe string. This kind of kelly and turntable The structure is complex, the volume is large, and the steel wire rope needs to be checked and replaced regularly, which poses a safety hazard; at the same time, the driller on the dri...
